How common is wake turbulence?

Wake turbulence is not just common, it's automatic. The magnitude at which it can affect another aircraft is less so and determined by how heavy an aircraft is, and how fast it is going. You can experience a low magnitude wake turbulence in a small private aircraft if you can execute a tight, level turn.

AVOID THE AREA BELOW AND BEHIND THE WAKE GENERATING AIRCRAFT, ESPECIALLY AT LOW ALTITUDE WHERE EVEN A MOMENTARY WAKE ENCOUNTER COULD BE CATASTROPHIC. A common scenario for a wake encounter is in terminal airspace after accepting clearance for a visual approach behind landing traffic.

Pilot Action to Mitigate Wake Turbulence Encounters: Approximately 10-30 miles after passing 1,000' below opposite-direction traffic. Approximately 10-30 miles behind and 1,000' below same-direction traffic.

Pilots review en-route conditions before departure, which include turbulence charts. This, alongside checking with center controllers about ride conditions while in the air, helps inform pilots about the flight conditions. Unlike other forms of turbulence, wake turbulence is predictable.

Turbulence is a sudden and sometimes violent shift in airflow. Those irregular motions in the atmosphere create air currents that can cause passengers on an airplane to experience annoying bumps during a flight, or it can be severe enough to throw an airplane out of control. (The pilots) aren't scared at all.

While pilots can't actually see turbulence, they often know what is coming up, thanks to reports from other planes, weather reports, and radar equipment. However, clear air turbulence (severe turbulence occurring in cloudless areas) can sometimes catch pilots off guard.

A light quartering tailwind requires maximum caution, as it presents a worst case scenario where a wake vortex could more likely be present along the final approach and TDZ. Pilots should be alert to larger aircraft upwind from their approach and takeoff flightpaths.

However, the vortex strength from an aircraft increases proportionately to an increase in operating weight or a decrease in aircraft speed. Since the turbulence from a “dirty” aircraft configuration hastens wake decay, the greatest vortex strength occurs when the generating aircraft is HEAVY, CLEAN, and SLOW.

Wingtip vortices make up the primary and most dangerous component of wake turbulence. Wake turbulence is especially hazardous in the region behind an aircraft in the takeoff or landing phases of flight. During take-off and landing, an aircraft operates at a high angle of attack.

The heavier the aircraft is and the slower it is moving, the stronger the vortices. That means that heavy aircraft such as a the Boeing 747 — and of course the Airbus A380, which is even bigger and heavier — are most prone to generating this kind of effect.

In addition, if flying over large areas of land, day-time temperatures can rapidly increase, creating convection air movement and thus turbulence, so travelling in the early morning before temperatures get high can avoid this turbulence.

Is turbulence better at night? Nighttime or morning flights are statistically better for turbulence, compared to those in the day.

In short, pilots are not worried about turbulence - avoiding it is for convenience and comfort rather than safety. In the best circumstances, pilots can forecast where turbulence is and steer clear of it. “We use met data and forecasts for jet streams to avoid potential areas,” the pilot said.

Wake turbulence from a large enough aircraft will cause the one following to flip and possibly crash into the ground.

While turbulence can feel scary, airplanes are designed to withstand massive amounts of it. A plane cannot be flipped upside-down, thrown into a tailspin, or otherwise flung from the sky by even the mightiest gust or air pocket, wrote pilot Patrick Smith on his site, AskThePilot.com.

The stronger the wind speed (generally, a surface wind of 20 knots or higher is required for significant turbulence), the rougher the terrain and the more unstable the air, the greater will be the turbulence. Of these factors that affect the formation of turbulence, stability is the most important.

A poll taken on A Fly Guy's Cabin Crew Lounge, the largest network of airline staff on social media, revealed that most airline crew not only like turbulence, but they also enjoy it! That's a comforting thought to think about the next time you're worried when your plane starts shaking. '

Usually the pilots will leave the autopilot engaged. In small airplanes with limited autopilots, it is better to fly manually, but with more sophisticated airplanes the autopilot is a valid option in turbulence. Severe turbulence is actually very rare.

Sometimes it's unavoidable to fly through light and moderate turbulence, but rest assured your pilots are working to find smooth air. If they encounter severe or extreme turbulence not forecasted, pilots will quickly climb or descend to a safe and smooth altitude.”
